The ARP can acquire up to ten targets
automatically by setting an automatic acquisition
area. When automatic acquisition is selected
after acquiring targets manually, only the
remaining capacity for targets may be
automatically acquired. For example, if seven
targets have been manually acquired, three
targets may be automatically acquired after
switching to automatic acquisition.
